摘　　要：针对七矿底板突水可能造成的危害,对21160风巷和机巷利用瞬变电磁方法探查了己组煤底板寒武灰岩含水层的赋水性。根据探测的数据推断6处可能富水异常区,综合对比现场的探测条件和地质资料,确定三处为富水异常区,为煤矿的安全生产提供了技术支持。To solve water disasters of the Cambrian limestone in the seventh Coal Mine, the transient electromagnetic method were used to explore aquifer＇s waler-bearing of the Cambrian in the ventilation entry and conveyor entry of 21160.Based on the detection of data, 6 possible water-rich areas are concluded, three water-rich areas are identified, eomprehensive comparing field exploration conditions and geological data and it provides technical support for the safe production in coal mines.
